Hey it is called the Shock Rocket before it reaches Electro-Rocket when it reaches V4 so really he didn't get it wrong so don't go around calling people noobs for something like that. It's perfectly reasonable someone might call the fully upgraded Electro-Rocket its original un-upgraded name- the Shock Rocket- especially if he only just upgraded it to the Electro-Rocket so he's not quite used to calling it the "Electro-Rocket" yet.

First time I fought him, I used the rockets once I took down his shield... They did pitiful damage (Even at E;ectro-Rocket level), and I kept dying. I wrnt back and upgraded the Laser Tracer to V2, and just used that and the PDA, and won on my second try using that combination!

That's only because it has a pitiful locking system for the rockets, only 1 or 2 of the 6 actually hit him! Just get it to V4, it becomes ludicrously powerful and can even kill Mungo in 3 hits! (Kills Otto in 30-35 hits including shields in my experience ) Very strong, overpowered and finally a great locking-on system! oh and it shoots 7 instead of 6, and they are all better than the original rockets, since they contain dark-matter in the warheads
